I have version 2. There is no sub-folder for the skin. I dragged the Darkness v1.1.r2skin file over Rainlender and a message said it was installed. It created a 1 file in the skin folder. This is a copy and paste from the log file:

You don't need them after the skin has been installed. And the zip shouldn't be in the skins folder in the first place. The r2skin installation goes like this:

- Download the Darkness1-1.zip and save it to your desktop.
- Open the zip and extract the Darkness v1.1.r2skin to your desktop.
- Double click on the Darkness v1.1.r2skin to install it.
- Refresh Rainlendar and select the skin from Options-&gt;Skins.
- Delete Darkness v1.1.r2skin and Darkness1-1.zip from your desktop.
